Joint Professor, Geosciences and
Ecology and evolutionary Biology

My research area is paleolimnology, the interpretation of lake history from sedimentary and paleontological records. Most of my work to date has involved studies of depositional environments, paleoecology, and climate history of the African Rift Lakes and the arid climate lakes of the western US. I use ostracode paleoecology and sedimentology as primary tools in the interpretation of lake deposits, from both outcrops and sediment core records.

Research Projects

I currently have major projects in the following areas:

• Change in Africa Paleoclimates and Paleolimnology of Lakes in the US Great Basin
• Deposystem Evolution in the Foreland Basin Lakes of South America
• East African Paleoclimate and Ecosystem History
• Implications of African Paleoclimates for Human History
• Lake Malawi Drilling Project
• Nyanza Project
• Paleorecords of Watershed Deforestation and Recent Climate
• US Great Basin Area Paleolimnology and Paleoclimatology

Courses

I am on sabbatical till June 2007. Normally I teach the following classes:

• GEOS 302-Principles of Stratigraphy and Sedimentology (Fall)
• GEOS412-Ocean Science (Spring, with J. Cole)
• GEOS 596D-Seminar. I offer seminars annually (usually in the spring semester) in paleolimnology, alternating every other year with more specialized subjects to be announced.
